The regulators aren't concerned about money laundering, except that they get their cut.
If they were, all the big banks would be shut down. They have already paid fines for money laundering. And we know they are continuing, because they have been fined again.
So, its not about money laundering, its about making sure the tax cattle cannot escape. All the little people have to stay and take their hair cut. (Like Crimea) While all the big boys, in the club, get to avoid such.
Fortunately, if the govern-cement does ban cryptos, it will only make them more valuable, and more people will use them. See any of the past prohibitions.
